The fastener uses a 3\/8-inch hex drive and features full threading along a 1-1\/4-inch length under head in a 1\/2-13 UNC thread size. Manufactured from alloy steel and finished with a black oxide coating, it provides corrosion resistance and a clean appearance. This screw meets ASME\/ANSI B18.3 and ASTM A574 standards, making it appropriate for demanding load applications. Machinists, millwrights, and maintenance technicians are the typical installers.\u003c\/p\u003e\u003cp\u003eThis screw is suited for general industrial assembly, machine building, and equipment maintenance where a recessed hex drive is required for flush or below-surface installation. The 1\/2-13 UNC thread is a coarse-pitch designation widely used in North American manufacturing. Full threading along the length under head maximizes thread engagement in through-hole and tapped-hole configurations. The black oxide finish is common in environments where moderate corrosion protection and low light reflection are priorities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/2-13 UNC coarse thread for broad compatibility with standard tapped holes\u003c\/li\u003e\n\u003cli\u003eFully threaded shank for maximum thread engagement\u003c\/li\u003e\n\u003cli\u003e3\/8-inch hex socket drive for use with standard hex keys and socket tools\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction for high tensile strength\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish provides moderate corrosion resistance\u003c\/li\u003e\n\u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM A574 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard replacement or service fastener for any application requiring a 1\/2-13 UNC hex socket cap screw with a 1-1\/4-inch length under head in alloy steel.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed with a 3\/8-inch hex key or Allen-style socket driver. Ensure the mating tapped hole is clean and free of debris before threading. Apply appropriate thread lubricant or anti-seize compound as required by the application.
